The utility model belongs to the technical field of oil storage devices, in particular to a constant temperature oil tank. Oil tanks are widely used tools in chemical, petroleum, pharmaceutical, biological and other industries. Experiments and tests are carried out in the fields of chemistry, metrology, colleges and universities, electronic instruments, and scientific research institutions. Use a place where the temperature is controlled and the temperature is uniform to conduct constant temperature test or test on the sample or product. The constant temperature lees control system adopts PID automatic control and LED digital display, and its external circulating pump can output the constant temperature liquid in the lees to the outside, which expands the scope of application. The existing fuel tank constant temperature control effect is poor, the movement and use are inconvenient, the safety protection factor is low, and the cover cannot be automatically opened and closed. Therefore, it is very necessary to invent a constant temperature oil tank.

The purpose of the utility model is to provide a constant temperature oil tank, which solves the problems of poor constant temperature control effect of the existing oil tank, inconvenient movement and use, low safety protection factor, and inability to automatically open and close the tank cover. In order to achieve the above purpose, the utility model provides the following technical solutions: a constant temperature oil tank, including a fuel tank body, a plug, a gasket, an electric telescopic rod, a safety protection layer, a condensation pipe, a support seat, a hinged buckle, a roller, a battery, a constant temperature The controller, the heating pipe and the isolation copper plate, the oil filling hole of the oil tank body of the constant temperature oil tank is provided with a plug; the stopper is connected with the fuel tank body through the gasket; the isolation copper plate is fixed at the lower end of the fuel tank body; the isolation copper plate is fixed with an electric telescopic rod; The telescopic rod end of the telescopic rod is fixedly connected with the stopper; the condensing pipe and the heating pipe are arranged from left to right under the insulating copper plate of the constant temperature oil tank; the lower end of the oil tank body is fixedly connected with the support seat; the battery and the thermostatic controller are installed on the support seat ;There are four rollers around the lower end of the support seat; the rollers are fixedly connected to the support seat through hinged buckles; the cooling pipe of the constant temperature oil tank is electrically connected to the battery through the constant temperature controller; the heating pipe is electrically connected to the battery through the constant temperature controller; the outside of the oil tank body of the constant temperature oil tank With safety protection layer. In addition, a sealing ring is provided at the contact portion between the plug and the fuel injection hole of the fuel tank body. In addition, the outer side of the roller is provided with a wear-resistant rubber ring.

To sum up, the technical effects and advantages of the above-mentioned utility model constant temperature oil tank are as follows: the technicians set up the condensation pipe and the heating pipe under the isolation copper plate, and automatically control it by the constant temperature controller, the constant temperature oil tank has a good constant temperature effect; The telescopic rod drives the limiter to extend up and down, which can realize the automatic opening and closing of the cover, which is easy to operate and saves time and effort. Move and use.
